[Bug 56493] PresentationFontCache.exe crashes during .Net 3.51 SP1 installation

--- Comment #13 from Hans Leidekker  ---
I think I see the problem. The custom action is a deferred action that starts
the FontCache3.0.0.0 service which depends on certain .NET assemblies. .NET
assemblies can't be installed before native fusion.dll is installed (we
accidentally depended on builtin being loaded instead, which no longer works
after the PE conversion).

Installing assemblies was moved into InstallFinalize to fix that but these
deferred custom actions (the commit variety at least) still need to be run
after that because they may depend on it.
